Linux Terminal character color settings

When we write the program, we usually need the terminal to display the output of red or green color, so that the user can be more clearly prompt. Here is how the Linux system terminal colors are set:

The character color of terminal is controlled by escape sequence, it is the system display function in text mode, and the specific language is independent, Shell,python,perl, C, C + + etc. can be called.
The escape sequence starts with the ESC and can do the same with \033 (the ASCII code for ESC is 27 in decimal notation, equivalent to 33 in octal notation).

Display format: \033[display mode; foreground color; background colour m
Where the display method, foreground color or background color is not in order, any of them is not required.
system default color: \033[0m

Display mode: 0 (default), 1 (highlighted), 22 (not bold), 4 (underscore), 24 (non-underlined), 5 (blinking), 25 (non-flashing), 7 (inverted), 27 (non-inverting)

Foreground color: 30 (Black), 31 (red), 32 (green), 33 (yellow), 34 (blue), 35 (magenta), 36 (cyan), 37 (white)

Background color: 40 (Black), 41 (red), 42 (green), 43 (yellow), 44 (blue), 45 (magenta), 46 (cyan), 47 (white)
